pycnometry singular

Morphology

pycnometry = pycnometer (opaque) = pycn + metry

The immediate base 'pycnometer' and the combining form 'pycn-' are highly technical and unlikely to be recognized by average learners, so the relation to 'density' is not readily derivable.

Etymology

Pycnometry comes from the Greek parts pycno- meaning 'dense' and -metry meaning 'measure', the same -metry you see in thermometer. So, pycnometry is the way to 'measure' how 'dense' a liquid is, for example by weighing it in a container of known volume.
